My research and teaching interests include Climate Change, Oceanography, Marine Ecology, and Biogeochemistry. I am also engaged in using marine science to inform policies directed towards solving key problems involving the oceans. My research group studies global environmental change with a focus on air-sea interactions, tropical marine ecosystems, polar climate change past and present, and the biogeochemistry of elements involved in life processes in the sea, e.g., oxygen, hydrogen, nitrogen, phosphorus, and carbon.
